This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X175-10, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X175-10
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X175-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 175mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X175-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X175-10
The AirTAC SIJ100X175-10 is a discontinued double-acting, double-rod adjustable-stroke ISO 15552 cylinder. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, giving a usable range of 165-175 mm. This stop sets the end position but is not a load lock.
The direct replacement is the SAIJ100X175-10, matching the interface, force, and mounting. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Without a -S suffix, this SKU cannot take a magnetic switch.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X175-10 Is Used
Press Fit Tuning
Dialing in a 165-175 mm extend for light press-fit operations where a fixed 175 mm stroke risks over-travel.
Transfer Stop Adjust
Trimming the extend stroke by up to 10 mm on-site to fine-tune a diverter gate without machining spacers.
Pallet Positioning
Adjusting the end-stop for varying pallet widths where a 10 mm external stroke correction is needed.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X175-10 with the SAIJ100X175-10
To replace the discontinued SIJ100X175-10, use the SAIJ100X175-10 direct. Reuse FA, LB, or TC ISO 15552 mounts. This non-magnetic SKU cannot take a switch. For strokes >=300 mm, verify side-load limits. The stop screw sets end position; it is not a lock, so use an external rod lock for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X175-10
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X175-10 FAQ
Yes, the SIJ100X175-10 is discontinued. The direct replacement is the SAIJ100X175-10, offering the same ISO 15552 interface, 175 mm stroke, 10 mm adjust window, and G1/2 port.
The external stop screw offers a 10 mm adjust window (usable extend 165-175 mm). The stop sets end position and is not a load lock.
